ENT Season 2 Episode 2 Carbon Creek

Plot

Captain Archer, Commander Tucker and Sub-Commander T'Pol are having dinner to celebrate the first anniversary of T'Pol's assignment aboard Enterprise. During conversation, Archer asks why T'Pol traveled to Carbon Creek, Pennsylvania, before she joined Enterprise. T'Pol reveals that, contrary to human belief that the first contact between humans and Vulcans occurred in the mid-2060s[a], it actually occurred a century earlier. Tucker and Archer react incredulously to this claim, so T'Pol offers to tell them her great-grandmother's story.
T'Mir is a member of a four-Vulcan crew studying Earth from orbit in 1957, when they witness the launch of Sputnik, the planet's first artificial satellite. A mishap with their impulse manifold forces the craft to crash-land in Pennsylvania. The captain is killed and T'Mir, as second-in-command, takes charge. A distress signal is sent, but after more than two weeks no reply is received. From fear of starvation, Mestral and T'Mir enter the nearby town of Carbon Creek, Pennsylvania. Over the next few months, the Vulcans successfully integrate themselves with the townsfolk, renting an apartment from Maggie, a tavern owner.
One day there is a firedamp explosion in the mine; Mestral helps rescue a dozen trapped miners by covertly blasting through a rock wall with a phaser. Eventually, a Vulcan vessel signals that it will arrive to retrieve the crew. Before leaving, T'Mir learns a human lesson in compassion, and travels by train to Pittsburgh where she "sells" the rights to Velcro. The money she receives is more than enough to pay for the college education of their landlady's son. As the Vulcan ship nears, Mestral announces that he intends to stay on Earth and observe the great advances he expects lie ahead. T'Mir reluctantly agrees, and tells the rescuers that Mestral had died along with the captain. T'Pol leaves Archer and Tucker unsure whether or not to believe the story. In her quarters, she reveals she still has T'Mir's 1950s-era handbag.
